HINGE T 0 all whom "it may concern:

Be it known that I, CHAUNCEY B. TRUM- BLE, a citizen of the UnitedStates of America, residing at Syracuse, in the county of Onondaga andState of New York, have invented new and useful Improvements in Hinges,of which the following is a specifica tion.

The invention relates to an improvement in hinges of the type designedfor use with screen or similar doors.

The main object of the invention is the production of a hinge in whichthe leaf adapted to be secured to the door frame is con structed topermit its convenient removal or attachment to said frame without thenecessity of removing the holding elements.

The invention will be fully described in the following specification,reference being had to the accompanying drawings, in which:

Figure 1 is a plan of the preferred form of hinge constructed inaccordance with my invention, the parts being shown in secured position.Fig. 2 is a similar view of the detachable leaf with the parts shown inposition to release the same from the frame. Fig. 3 is a sectional viewillustrating particularly the hinge securing means connected to theframe. Fig. 4 is a plan of a modified form of hinge in applied position.Fig. 5 is a side elevation of the same. Fig.6 is a section on line 6-6,of Fig. 4.

Referring particularly to Figs. 1, and 3 of the drawings wherein isshown the preferred form of the invention, my improved hinge comprisesleaves 1 and 2, the former being designed for attachment to a screendoor by means of the usual screws 3, and will be hereinafter termed thefixed leaf, while the remaining leif 2 is adapted to be secured forattachment to the door frame, and will be hereinafter referred to as thedetachable leaf.

The invention is particularly adapted for forming the detachable leaf topermit its convenient attachment to and removal from the door framewithout the necessity of detaching the connecting elements therefor. Tothis end the detachable leaf is centrally formed with an elongatedopening at, and be tween the ends of said opening and the edges of theleaf with keyhole openings 5, the reduced portion 6 of which project inthe same direction longitudinally of the leaf.

To the door frame in position to engage the Specification of LettersPatent.

Application filed May 16, 1907.

Serial No. 373,938.

detachable leaf 2 are secured pins 7 corresponding in diameter with thereduced portion 6 of the keyhole openings and so spaced as to permitsimultaneously insertion in said openings in the application of theleaf. Between the pins 7 is arranged a turn button 8, the relativelyinner surface 9 of which is normally spaced from the door a distanceequal to the thickness of the detachable leaf, while said turn button isslightly less in length and width than the similar dimensions of theopening 4.

In applying the hinge to the door frame after application of the fixedleaf to the screen door, theturn button 8 is arranged longitudinally ofthe frame, and the detachable leaf placed in position with the pin 7 inthe keyhole openings and the turn button projecting through the opening41-. The hinge is then moved longitudinally to dispose the pin 7 in thereduced portion of the keyhole openings, and the turn button 8 arrangedtransversely of the leaf so that it overlies and bears upon the sidewalls of the opening 4 in position to securely bind the leaf to theframe.

If preferred, the pin 7 may be headed in the usual screw form, with theheads of greater diameter than the width of the reduced portion 6 of thekeyhole slots, so that after application of the hinge as described, thepins may be slightly turned to securely bind them onto the outer surfaceof the leaf.

In Figs. 4 and 5 is shown a slightly modified form of leaf in which thedetachable leaf 10 is centrally offset to provide a plate 11 from theends of which depend side portions 12, terminally projected laterally toprovide lips 13. The plate 11 provides in effect the leaf portion towhich the fixed leaf 14.- is socured, while the lips 13 are designed tobear upon the frame structure and to be removably secured thereto. Thelength of the side portions 12 of the leaf are equal to the thickness ofthe door into which the fixed leaf is secured, so that the hinge of thisform is particularlyadapted to dispense with the usual blocks securedupon the frame to offset the hinge of the ordinary type in securing thescreen door in place.

In the modified form of hinge the respective leaves 13 are formed withkeyhole openings 14, preferably arranged in pairs in each leaf, thereduced portions 15 of the openings being of less diameter than theheads 16 of the screws with which this form of hinge is secured inplace. By preference the wall of the enlarged portion of each keyholeopening immediately adjacent the opening is formed with an offset orprojection 17, which at the juncture of the enlarged portion with the reduced portion 15 coincides with the surface of the lip, and from thispoint said projection gradually increases or inclines upwardly towardthe remote point of the enlarged portion. The projections preventbinding of the screw on the edge of the enlarged portion of the openingin securing the hinge in place.

In the modified form the screws 16 are loosened and the hinge engagedtherewith by inserting the heads of the screws through the enlargedportions of the openings. The hinge is then moved downward to cause theshanks of the screws to enter the reduced portions, after which thescrews are tightened to secure the hinge in place. As the screws requirebut a half turn to permit the application of the hinge, it is obviousthat the projecting wall 17 of the enlarged portion of the opening willextend above the heads of the screws, as shown in Fig. 6, therebypreventing the screws from engaging the wall of the opening.

In both forms of hinges the detachable leaf and fixed leaf are eachprovided with proj ecting ears 18 formed with openings adapted to bealined to receive a pivot rod 19. A spring 20 is coiled about the rodwith the ter minals 21 projecting in opposite directions and bearingupon the respective leaves, thereby providing a simple form of springhinge.

The hinge of my invention is adapted for ready connection to ordisconnection from the frame, permitting the application or removal ofthe hinge and connected door without the necessity of removing thesecuring means by which the hinge leaf is connected to the frame. Theseconnecting members will therefore remain in position, insuring theapplication of the door when the same is hung in correct position.

Having thus described the invention, what I claim is:

1. A hinge comprising a detachable leaf and a fixed leaf, a springconnection between the leaves, the leaf being formed with keyholeopenings arranged in longitudinal alinement, the reduced portions of theopenings projecting in the same direction, and pins projecting from afixture and adapted to engage the reduced portion of the keyholeopenings and secure the hinge in applied position.

2. A hinge comprising a fixed leaf and a detachable leaf, the detachableleaf being centrally offset, the fixed leaf being approximately equal inlength to the length of the offset portion of the detachable leaf, aspring connection between the leaves and serving to normally maintainthe fixed leaf in the plane of the offset portion of the detachableleaf, said detachable leaf being formed beyond the offset portion withkeyhole openings to receive pins projecting from the structure.

3. A hinge comprising a fixed leaf and a detachable leaf, the detachableleaf being centrally offset, the fixed leaf being approximately equal inlength to the length of the offset portion of the detachable leaf, aspring connection between the leaves and serving to normally maintainthe fixed leaf in the plane of the offset portion of the detachableleaf, said detachable leaf being formed beyond the offset portion withkeyhole openings to receive pins projecting from the structure, theenlarged portion of the keyhole openings being formed with a wallprojecting above the plane of the contiguous portion of the leaf, saidprojection inclining toward the reduced portion of the keyhole opening.

In testimony whereof, I affix my signature in presence of two witnesses.
